WATER-HEATER.

Specification of Letters Patent.

Patented Nov. 17,' 1908.

Application tiled January 10, 1908. vSerial No. 410,144.

To all 'whom 'it may concern:

. Be it known that I, HERBERT S. HUMr United States, residing at the city and county of Kalamazoo, State of L chigan, have invented certain new and useful Improvements in Water-Heaters, of which the following is aspecilication.

This invention relates to improvements invl gas burners.

My improved gas burner is particularly adapted and designed by me for use in water heaters, such as illustrated in my application for Letters Patent filed September 12, 1907, Serial No. 392,595, although it is desirable and adapted for use in various other relations where a heating burner is desired. The main objects of this invention are,-

First, toprovide an improved gas burner for heating purposes which is-of large capacity, and, at the same time, one which secures a very perfect combustion of gas. v-Second, to provide an improved burner for water heaters and the like which is effectively protected from water dripping from above. Third, to 'provide an proved burner in which the partsare so arranged that they do not become overheated when in use, thereby obviating to a large extent the liability of backlighting or backfiring. Fourth, to providean improved burner possessing these advantages `which is very veconomical in structure, and is very durable 1n use.

Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.`

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out. in the claims.

my invention is clearly illustrated in the accompanying drawing, forming a part kof this specification, in whic Figure 1 is a detail view on aline corresponding to line 2 2 l. Fig. 3 is a the burner,

a line corresponding taken looking in the direction V,of the little' arrows at the ends of the section lines, and

Iwhereby the burners vA structure embodying the features of.

of a water heaterff provided with my improved burners. Fig. 2'. is an enlarged detail vertical section, ftaken v 0 Fi plan ,viewV of the cap-plate gf looking in the direction of the arrow above Fig. 2. Fig. 4 isa cross section Pulg similar numerals of reference refer to simi-Y lar parts throughout the several views.

Referring to the drawing, 1 represents the base; 2 the burner chambers; and 3 the Water coil chamber of a water heater Such as I have illustrated in my application for Letters Patent hereinbefore referred to. The water coils 4 arearranged in the water coil chamber 3 above the burners. These burners are grouped in the burner chamber, preferably arranged on the gas delivery 5, which is supplled from a pipe, as 6.

VIn order to more effectively group the burners, the ring is preferably provided with arms 7, part of which project inwardly 'and part outwardly, the gas delivery nozzles, as 8, being located on these arms. Y

My improved burners preferably consist of the burner tubes 9 having cross-pieces 10 at their lower ends, the cross-pieces being perforated to receive the delivery nozzles Y8,

burner tubes 9 are preferably provided with upwardly contracted mixing chambers, as 11, at their lower ends and upwardly-expanding expansion chambers 12 at their 11pper ends, the upper ends of the tubes be' expanded-to form enlargements or delivery chambers, as 13, these delivery chambers bei ing preferably elongated.

The cap-plate 14 for the enlargement or delivery chamber -13 of the burner tubeis preferably arranged in ,an inclined position, as is illustrated in the drawing, the plate being preferably a Hat plate adapted to be securedto the head by means of suitable screws, as 15. The plate 14 is provided with a plurality of jetor burner tips 16 which project laterally therefrom. These jet or burner tips are preferably arranged in Zigzagged series, as clearly appears in Fig. 3. rEhe mouths of these burner tips preferably lie in substantially vertical planes, thereby Securing an overhanging lip or projection, which guards the burner from water drip from above, and also directs the jets or flames outwardly. These burner tips are arranged in an-inclined position, those of the lower series projecting outwardly beyond those of the u per series. The burner ti s being zi' zagg permits a free passage of) air to a of. the tips, and also more effectively distributes the heat. The llames, by this form of burner tips, are directed away from the cap-plate, so that it does not become excessively heated when the burner is in use, and by thus arranging the burner tips, backlighting is lar ely prevented. To further guard against backlighting, I provide a screen, as 17. This screen is preferably located against the inner side of the cap-plate, it being clamped in position thereby, thus not only securing a very effective means for holding the screen, but the same is located in a desirable position as well.

I have illustrated and described my improved burner in detail in the form preferred by me on account of its structural simplicity and economy, -and its effectiveness in use. I am aware, however, that it may be very considerably varied in structural details without departing from my invention,

and still produce a satisfactory structure,

and I desire to be understood as claiming the invention in the embodiment illustrated as well as broadly. Itis desired to remark in this connection that in'practice the mouth of the burner must be made a proper size to correspond with the amount of gas delivered by the gas delivery nozzle, and the mixing tube must correspond or be properly proportioned.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent is: 1. An upright burner comprising a burner tube having an enlargement or head at its upper end; an inclined cap-plate therefor,

said cap-plate being 4provided with a plurality of laterally-projecting jet or burner tips-arranged in-z1gzagged series, the delivery openings or mouths of said tips being in substantially vertical planes; and a screen arranged across said head beneath said capplate and clamped in position thereby.

2. An upright burner comprising a burner tube having an enlargement or head at its upper end; and an inclined cap-plate therefor, said cap-plate being provided with a' plurality of laterally projecting jet or burner tips arranged in zigzag ed series, the delivery openings or mouths o said tips being in substantially vertical planes.

3. Anupright burner comprising a burner l tube having an enlargement or head at its upper end; an inclined cap-plate therefor, said cap-plate being provided with a'plurality of laterallyprojecting tubular jet or burner tips, the delivery openings or mouths of vsaid tips being in substantially vertical planes; and a Iscreen arranged across said head beneath said cap-plate and clamped in position thereby.

4. An upriUht-burner comprising a burner tube. having 2Inenlargement or head at its upper end; an inclined cap-plate therefor,

said cap-plate being provided with a plural- 'ity `of laterally-projecting tubular jet or burner tips, the delivery openings or mouths of said tips being in substantially vertical planes. J

5. A burner comprising a. burner tube; a cap-plate therefor, said plate being inclined ing jet or burner tips arranged in a zigzagged series, the. delivery. openings or .mouths of said tips being 1n substantially to the longitudinal axis of saidburn'er tube and having a plurality of laterally-projectand a cap plate therefor, said plate being-inclined to the longitudinal axis of said'burner, tube and having a plurality of separated-v projecting jet or burner tips arran ed 1n a zigzagged series, to permit the circu ation of air Varound the same; the delivery openin or mouths of said ltips being in substantial y verticalplanes.

7. A burner comprising a burner tube; a cap plate therefor t0 the longitudinal jet or burner tips, the delivery openings or mouths of said tips being-in substantiallyvertical planes; and a screen arrangedv clined to the longitudinal axis of said burner.

tube and-havin a `plurality of separated projecting tubu ar jet or burner tips, ar.

said plate being inclined v axis of said burner tubeand having a plurality of projecting tubular ranged topermit free circulation of air around the same; the delivery y1o enngs or mouths of said tips being in su s'tantially vertical planes.

In witness whereof, I have hereunto slet` my hand and seal in the presence of two witnesses. l
